Abstract

A system for the secure transmission of messages that may be included with existing automated message handling software applications. The secure transmission system includes a user interface tool that appears with the user interface of the conventional automated message handling system. A digital key generator and encryption engine is responsive to the user interface tool. Upon creating an addressed message using the conventional user interface of the automated message handling application, the user can select the user interface tool to activate the digital key generator and encryption engine that in turn generates a secure file containing the message content and address. The system further includes a message generator that generates a message to a secure message-handling server. The secure message includes the secure file and the digital signature of the secure file. The secure email, when received by the secure message-handling server, is prepared for secure delivery to the addressee of the message.

Claims

1. An electronic mail system comprising:

an email application having an interface for selectively initiating a first email sending process or a second email sending process for an email having content;

a first email server that routes the email content toward an intended recipient without encrypting the email content when the first email sending process being initiated via the interface; and

a second email server that initiates a secure message transaction for delivering the email content to an intended recipient when the second email sending process being initiated via the interface, the secure message transaction including providing secure access to the email content, irrespective of whether the intended recipient'"'"'s email application is decryption enabled.

2. An electronic mail system according to claim 1 wherein the second email server causes an SSL link to be sent to the intended recipient via an email protocol, the SSL link when activated providing access to the email content.

3. An electronic mail system according to claim 1 further comprising a firewall, wherein the email application, first email server and second email server reside on a secure side of the firewall.

4. A method for transmitting an email comprising the steps of:

launching an email application, the email application including an interface;

selecting one of a plurality of email transmitting processes via the interface;

if the selected email transmitting process requires secure message transmission to a recipient, inserting email content into an electronic message addressed to a server that initiates a secure link with the recipient.

5. The method of claim 4 comprising the further step of providing the recipient access to the email content via the secure link.

6. The method of claim 4 wherein the inserting step includes the steps of attaching a document file having the email content to the electronic message, the email content including address information and message information for the email.
